wen-* `IMIPROVElMENT IN BELL-PULLS.

m The Schedule referred to in lthese -Letters Patent and making part ofthe same.

. LJ ons JOSEPH CHARLES SMITH,'oi` Somerville, in

the county of Middlesex, and State of Massachusetts, have invented a newand improved Bell-Pull, which is described as follows:

Nature and Objects of the Invention.`

My invention is intended primarily, though not eX- o1usively,for outsidedoor-bells; and consists, essentially, ofa cylindrical hub, having apartial rotation in 'a plane perpendicular .to the wall or other surfaceto which thebell-pull is applied, and operated by a knob,

projecting from the hub in a direction coincident with the plane of itsrotation, the saidhub being constructed with concentric segmentalflanges, which project from one end or faceplate of the hub, in suchainanner as to adapt the wholefor casting. Ot' these segmental anges,one serves for the attachment of the bell-wire 0r chain, and a helicalspring, which retracts the knob when released; and the other to mask orclose the recess' in which the hub works, all as hereinafter described.

General Descriptiony ywith Reference to the Drawing.

B. B, forming the bearings or attachments of an arbor, C, upon which thehub D turns.

The handle E, for turning thehnb, rises'obliqnely from it, andterminates in a knob, F, projecting horizontally.

The bell-chain G Vis attached: to a stud, h,- upon a segmental flange,H, at the other end of the helical spring I, whose Ainnerlend isattached to the arbor O,

so as to restore the parts to their normal position, represented in iig.1, when the knob is released.

The outer concentric ilange J serves to mask or cover the recess inwhich the, hubworks, and all the various parts of the rotating hub, withits handle E F, are' so constructed and arranged that they may bereadily cast in onepiece, by means ofjmy compresserprocess, described inLetters Patent heretofore granted.

The 'handle projects in such a position, that `a person desiring to pullthe'bell, whether familiar with the construction ofthe device ornot, indrawing the knob outward from the wall, willalso bear downward, so thata child, or other person with little strength, can, with great ease,apply all needful force to ring the bell.

`I claim, as my invention-'- The hub D, constructed with' the concentricseg? mental'anges H J, handle E, and knob F, and eniployed in connectionwit-li the arbor C and helical spring I, all applied and' arranged asand for the purposes set forth.
